RESEARCH
非線形動力学。非平衡開放系の自己組織化現象、特にリミットサイクル振動子の集合体、ネットワーク、連続場等における同期現象や波動現象の理論的研究。同分野への主な寄与として、位相縮約理論の開発、集団同期現象の可解モデルに提出、位相乱流現象の発見等。

Received PhD degree from Kyoto University. His academic positions before March 2015 include: Professor of Kyoto University, Specially Appointed Professor of Hokkaido University, Vice Director of International Institute for Advanced Study etc. His current position is Professor Emeritus of Kyoto University. He has worked on theoretical nonlinear dynamics with particular interest in various self-organizing phenomena of coupled oscillator systems in non-equilibrium open systems. His main contribution to this field includes the proposal of a solvable model for collective synchronization and of a partial-differential equation model describing phase turbulence, and publishing the monograph “Chemical Oscillations, Waves, and Turbulence” from Springer-Verlag.
